Even for folks who aren’t familiar with rooting and ROMing, Vivo makes it pretty easy to install Android P on the Vivo X21. You just need to download the image from Vivo’s developer site, copy it to a folder on your device, and open it. That’s a welcome change from other devices, like Essential Phone, which make you jump through hoops to install Android P.

There are two versions of Vivo X21: the regular version known simply as Vivo X21 and a version with an under-display fingerprint scanner known as Vivo X21 UD. Luckily, both versions share the same process of flashing Android P beta. You don’t need to worry about file versions either, as both models use the same image.

Without further ado, here’s how to install Android P on the Vivo X21 and Vivo X21 UD.

How to get Android P beta on the Vivo X21/UD

Before you begin, make sure to back up all the data you want to keep, as the Android P installation process wipes the phone.

Here are the Android P installation instructions, as outlined by Vivo on its developer website:

Step 1: Download the Android P beta (developer preview) image by clicking on this download link. You need to download the image on your computer. The file is called “PD1728_A_3.0.13-update-full_1525666147” and is roughly 2.3GB in size. Pro tip, start downloading as soon as you can, as transfer speeds are pretty low.

Step 2: Connect your phone to the PC via microUSB (in file transfer mode) and copy the downloaded system image to the top (“root”) directory of the phone’s internal storage.

Step 3: Using the phone’s default file manager, navigate to the downloaded system image on your Vivo X21 and tap on the file. This should begin the installation process.
